Answer:
They are deposits of silt and mud carried by the wind.
They are found in regions close to but outside areas of glaciation.
There are deposits in Europe, North America, China, and Argentina.
Explanation:
Loess was first discovered and coined in Europe and refers to an important component of the soils of the European Plain. Loess consists of particles of silt, clay, and mud that have been carried by the wind and eventually deposited to form extensive formations.
Loess layers are not only deep but also conducive to agriculture as they are also fertile. Perhaps the most common source of loess is the glacial activity since the movement of glaciers produces a large amount of finely ground sediment on the fringes that is later picked up by the wind.
Answer: True
Central America has had difficulty in finding a good political and economic balance following centuries of domination by European nations because the people of Central America were not united. Corruption had been one of the main obstacles to development in Central America and the inability of the government to eradicate corruption resulted in political and economic instability.
<u>Answer</u>:
<em>A break that isolates more seasoned changeable rocks from more youthful sedimentary shakes promptly above them is a sort of unconformity called a nonconformity.</em>
<u>Explanation:</u>
<em>A rebelliousness is a break that different previous (changeable rocks or volcanic rocks) from overlying sedimentary rocks.</em>
An nonconformity is a contact between two shake units where the upper unit is are commonly covered erosional surfaces that can speak to a break in the geologic that isolates a more youthful sedimentary shake unit from a molten meddlesome <em>shake or shake at the surface before it was at long last covered by the more youthful shakes above it.</em>
Answer:
- Shape of the continents
- Fossils of the same species found on continents that are not connected
- Evidence of ice sheets in places that are hot in the present
- Mid-ocean ridges
Explanation:
The continental drift theory is a theory that suggests that the continents are always on the move, thus they change their shape, location, collide with each other, move away from each other etc.
The shape of South America and Africa is one of the evidences. If the shapes of the continents are taken out of a map, and the eastern coast of South America and western coast of Africa are merged, they fit in perfectly.
There are numerous fossils of the same species of animals and plants that have been found all over the world, even though the continents are isolated and separated by water bodies.
In some places that are very hot in the presence, like South Africa, have evidence of ice sheets. In the current conditions that is simply not possible considering that the temperature in this part of the world goes well over 40 C degrees.
The mid-ocean ridges are very nice proof of the continental drift theory. They are one of the evidence that can be observed in the present, where new crust is constantly forming and pilling up, while pushing the old crust sideways further away from it.
